Essential oils from the stems/leaves (L) and flowers (F) of Lavandula stoechas L. ssp. growing wild in southern Sardinia (Italy) were extracted by hydrodistillation analyzed gas chromatography coupled with flame ionization detector ion trap mass spectrometry. The major compound was fenchone, accounting for, on average, 52.60% L 66.20% F, followed camphor (13.13% versus 27.08%, respectively). F essential oil yields (volume per dry weight) decreased beginning to end flowering stage, whereas...
Quince (Cydonia oblonga Miller) fruit aqueous acetone extracts were evaluated. High-performance liquid chromatography−diode array detection and electrospray ionization−mass spectrometry used for the identification quantification of phenolic compounds. The total content pulp peel parts ranged from 37 to 47 105 157 mg/100 g fresh weight, respectively. Chlorogenic acid (5-O-caffeoylquinic acid) was most abundant compound in (37%), whereas rutin (quercetin 3-O-rutinoside) main one (36%). radical...
The chemical composition of the essential oil Sardinian Rosmarinus officinalis L. obtained by hydro distillation and steam\hydro was studied using GC-FID MS. Samples were collected at different latitude longitude Sardinia (Italy). yields ranged between 1.75 0.48% (v/w, volume/dry-weight). A total 30 components identified. major compounds in α-pinene, borneol, (−) camphene, camphor, verbenone, bornyl-acetate. Multivariate analysis carried out on molecular markers, with appraisal chemical,...
The extraction procedures (solid/liquid SPE and liquid/liquid LLE) HPLC separation quantification methods of polyphenolic compounds have been checked in virgin olive oils order to explain the differences content reported literature. work has carried out on prepared from one cultivar produced under same protocol. are practically equivalent, but technique is more favorable because it faster simpler. It proved that chromatographic features method chemical expression concentrations may greatly...
The composition of the essential oil from ripe and unripe berries leaves Juniperus oxycedrus L. ssp. oxycedrus, phoenicea turbinata communis was analyzed by GC-MS, microbiological assays were carried out. Samples collected in different localities (Sardinia, Italy) hydro distilled. yields ranged between 2.54% +/- 0.21 (v\w dried weight) 0.04% 0.00. A total 36 components identified. major compounds oils alpha-pinene, beta-pinene, delta-3-carene, sabinene, myrcene, beta-phellandrene, limonene,...
An apiary trial on the use of two acaricide formulations (gel-Apiguard and vermiculite Api Life VAR) in control Varroa destructor (Anderson & Trueman) was conducted summer 2001 Sardinia (Italy). The main goals were 1) to determine their effectiveness against V. destructor, taking into account natural mite mortality hives; simultaneously 2) persistence both residues honey wax, by using a new extraction method. Both thymol formulations, after treatments, reduced significantly levels...
Essential oil (EO) from aerial parts (leaves, juvenile branches, and flowers when present) of Pistacia lentiscus L. growing wild in five localities Sardinia (Italy) was extracted by steam-distillation (SD) analyzed gas chromatography (GC), FID, GC-ion trap mass spectrometry (ITMS). Samples P. were harvested between April October to study the seasonal chemical variability EO. A total 45 compounds accounting for 97.5-98.4% EO identified, major alpha-pinene (14.8-22.6%), beta-myrcene (1-19.4%),...
The disappearance of azoxystrobin, pyrimethanil, cyprodinil, and fludioxonil on tomatoes in greenhouse was studied. At the preharvest interval, except for pesticide residues were below MRL fixed Italy. mechanism studied with model systems shows that decrease due to codistillation photodegradation fludioxonil, evaporation cyprodinil. Azoxystrobin stable during all experiments.
The fate of four new fungicides (cyprodinil, fludioxonil, pyrimethanil, and tebuconazole) from the treatment on vine to production wine was studied. influence clarifying agents (bentonite, charcoal, potassium caseinate, gelatin, polyvinylpolypyrrolidone) residue concentrations in also fungicide residues grapes showed different decay rates after treatment, with first-order kinetics half-lives ranging 8 57 days. Grape processing into caused considerable reduction cyprodinil (ca. 80%),...
Strawberry tree honey, due to its characteristic bitter taste, is one of the most typical Mediterranean honeys, with Sardinia being largest producers. According specific chemical studies, homogentisic acid was identified as a possible marker this honey. This work, based on HPLC-DAD-MS/MS analysis strawberry (Arbutus unedo L.) previously selected by sensory evaluation and melissopalynological analysis, showed that, in addition above-mentioned acid, there were other high levels substances...
During the liquid chromatographic study of phenolic fraction monofloral honeys was detected in asphodel honey (Asphodelus microcarpus Salzm. et Viv.) chromatogram a distinctive peak not other such as Arbutus unedo L., Hedysarum coronarium, Eucalyptus spp., and Galactites tomentosa. After thin layer chromatography (TLC) purification characterization by NMR LC-MS/MS, compound identified methyl syringate (MSYR) confirmed against an original standard. Levels MSYR were measured 2005, 2006, 2007...
Essential oil (EO) from aerial parts of Eucalyptus camaldulensis Dehnh., growing wild in different localities Sardinia (Italy), was extracted by steam distillation and analyzed gas chromatography (GC) FID GC-ion trap mass spectrometry (ITMS). The yields EO (v/dry wt) ranged between 0.2-0.5%. Samples were harvested April December to study the seasonal chemical variability EO. composition varied depending on origins showed strong fluctuation during vegetative stage. Thirty-seven compounds,...
Analysis of organic acids in strawberry-tree (Arbutus unedo) honey showed the presence an unknown acid as main constituent. This compound was isolated and identified homogentisic (2,5-dihydroxyphenylacetic acid) by MS NMR techniques. Its average content 378 ± 92 mg/kg. nectar confirmed floral origin found honey. Since this not detected any different monofloral honeys, it could be used a marker (A. Keywords: Homogentisic acid; unedo); honey;
The influence of six fungicides (azoxystrobin, cyprodinil, fludioxonil, mepanipyrim, pyrimethanil, and tetraconazole) on the fermentative activity two yeasts (Saccharomyces cerevisiae Kloeckera apiculata) lactic bacteria (Leuconostoc oenos Lactobacillus plantarum) was studied. possibility their being degraded by these also investigated. presence pesticides did not affect alcoholic fermentation, even with levels higher than those normally found in grapes field experiments. On contrary,...
The decay rate of six insecticides (azinphos methyl, diazinon, dimethoate, methidathion, parathion and quinalphos) used to control Dacus oleae was studied. Degradation pesticides showed pseudo-first-order kinetics with correlation coefficients ranging between −0.936 −0.998 half-lives 4.3 days for dimethoate 10.5 methidathion. Residues in olive oil were greater than on olives, a maximum concentration factor 7. Dimethoate the only pesticide lower residues fruits. Olive washing affects from no...
Azadirachtoids were determined by liquid chromatography/mass spectrometry (LC/MS) in five methanolic seed extracts of the neem tree and a commercial formulation. On average, contain azadirachtin A (10.9%), B (3.5%), nimbin (10.4%), large quantities salannin (19.0%). The composition formulations may present different azadirachtoids contents depending on natural used preparation. Because these compounds also show insecticide activity, efficacy field be very different. Photodegradation pure was...
